Abstract
A new step-down topology featuring a static conversion ratios that makes it suitable in applications requiring an output voltage slightly lower than the input voltage is proposed. In those conditions the proposed converter still operates at moderate duty cycles exhibiting very good efficiency. Compared to quadratic topologies that are 4 th order system the new Buck converter is a second order system, thus allowing for easy loop design using the traditional approaches. A dc analysis is performed and main equations in steady state are provided together with a design example. Then the theoretical considerations are validated by computer simulation and finally the experimental results confirmed the feasibility of the proposed topology.
